Secret Code Addition with Thanksgiving — Grade 1

This Grade 1 worksheet turns addition into a code to crack. A legend gives each of the turkeys, pumpkins and a pie a secret number; on every row the child looks up the pictures, swaps in their numbers, and adds them together. Because each row adds three or more of these picture-numbers, it is exactly the Grade 1 step beyond two-addend sums — and the legend keeps the child decoding, not just calculating. Every total stays within twenty, so the answers are still ones a child can count to check.

Looking up each picture's value and then adding three or more of them rehearses both careful reading and multi-number addition at once. For a Grade 1 child that combination builds real confidence with small sums, and holding every total within twenty keeps the work honest — a child can always count the decoded numbers to check the answer rather than guess it, then move on to the next coded row.

Children who like thanksgiving treat each row as a small puzzle, which keeps a code-breaker happily adding. When this feels easy, crack the code in secret code addition with toys, or try secret code addition with accessories.
